Gallia Belgica (or Belgica Prima) was a Roman province located in what is now the southern part of the Netherlands, Belgium, Luxembourg, northeastern France, and western Germany.

The Remi were a Belgic tribe of north-eastern Gaul in the 1st century BC. They occupied the northern Champagne plain, between the rivers Mosa (Meuse) and Matrona (Marne), and along the river valleys of the Aisne and its tributaries the Aire and the Vesle. Their tribal capital was at Durocortum (Reims, France) and they were renowned for their horses and cavalry. The Remi, under Iccius and Andecombogius, allied themselves with Julius Caesar when he led the conquest of Gaul. The Remi tribe remained loyal to him throughout the entire Gallic Wars, the most pro-Roman of all the peoples of Gaul.

A Potin has no intrinsic value or standard weight. They were issued by tribes to use as a trade commodity and each type was usually only accepted within its own tribe.
